Check For Intermittent Problems [08/2020 - ]
WARNING: This page is about a different car, the 2025 Toyota RAV4, 2024 Toyota RAV4, 2023 Toyota RAV4, 2022 Toyota RAV4, and 2021 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
Inspect the vehicle ECM using check mode. Intermittent problems are easier to detect with the Techstream when the ECM is in check mode. In check mode, the ECM uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detection logic.
- Clear the DTCs.
Refer to DTC CHECK / CLEAR [08/2020 - 10/2022] , or refer to DTC CHECK / CLEAR [10/2022 - ]
- Change the ECM from normal mode to check mode using the Techstream.
Refer to CHECK MODE PROCEDURE [08/2020 - ]
- Perform a simulation test.
- Check and wiggle the harness(es), connector(s) and terminal(s).
